the point (9,-12) is also on the line

Step-by-step explanation:

by using the 2 points the equation is y=-4/3x

use x of 9

y = -12

it will also represent a direct variation function

so two of the 4 will be correct

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-1, 4)

Point (1, -1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $\displaystyle d = \sqrt{(1+1)^2+(-1-4)^2}$
Add/Subtract: $\displaystyle d = \sqrt{(2)^2+(-5)^2}$
Exponents: $\displaystyle d = \sqrt{4+25}$
Add: $\displaystyle d = \sqrt{29}$

What is measure of angle r

Leona [35]

Answer:

Answer: (1) The measure of angle T is 100 degrees --> since no other angle can be equal to 100 degrees (because in this case the sum of the angles will be more than 180 degrees) then the other two angles, R and S, are equal: R=(180-100)/2=40.Mar 21, 2020

The first CORRECT answer gets Brainliest. The hints are 1. Use subtraction to find the lengths of the sides of the small rectang

Zielflug [23.3K]

Answer:

128 ft^2. You are correct.

Step-by-step explanation:

The shape of the family room is a smaller rectangle above a larger rectangle.

We need to find the lengths and widths of both rectangles.

The length of the larger rectangle is 12 ft.

The width of the larger rectangle is 9 ft. You can see the sides labeled 12 ft and 9 ft right on the figure.

To find the length and width of the smaller rectangle on the top left, you need to subtract.

The length is 12 ft - 7 ft = 5 ft

The width is 13 ft - 9 ft = 4 ft

Now we find the areas using the lengths and widths, and we add them.

Area of large rectangle = L * W = 12 ft * 9 ft = 108 ft^2

Area of small rectangle = L * W = 5 ft * 4 ft = 20 ft^2

Total area of room:

108 ft^2 + 20 ft^2 = 128 ft^2

Answer: 128 ft^2
